ABSTRACT:
A polar transmitter includes a two-point modulation phase-locked loop (PLL) for producing an RF signal with a wide bandwidth. The PLL includes a first input for receiving a phase signal of a variable-envelope modulated signal and providing the phase signal along a first signal path to produce a first frequency modulation signal and a second input for receiving the phase signal and providing the phase signal along a second signal path to produce a second frequency modulation signal. The PLL further includes a voltage controlled oscillator (VCO) having two modulation points, one for receiving the first frequency modulation signal and the other for receiving the second frequency modulation signal. The VCO is controlled by an aggregate of the first frequency modulation signal and the second frequency modulation signal to up-convert the phase signal from an IF to an RF to produce the RF signal with a wide bandwidth.
